SPECIFICATION forming part of Letters Patent No. 402,149, dated April 30, 1889.

Application liled March 3, 1388. Serial No. 266,090. (No'model.)

To al? whom t may concern.-

Be 1t known that I, JOSEPH P. M. EARTY, a citizen of the United States, residing atPolk,

, in the county of Ashland and State of Ohio,

forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure I is a longitudinal vertical sectional view of a pump embodying my improvements. Fig. 2 is a horizontal transverse sectional View of the same, taken on the Iine fr of Fig. l. Fig. 3 is a similar view taken on the line y y of Fig. 1. Fig. 4is an enlarged. detail sectional View of the plunger.

A represents the outer cylinder, which is of suitable length and diameter, and is provided with external screw-threads at its upper and lower ends.

B represents a cap, which is substantially semi-.spherical in shape, and is provided at its lower edge with a depending internallythreaded iiange, C, which is adapted to be screwed to the upper end of cylinder A. An annular shoulder, D, is formed on the inner side of the cap, at the upper side of said iiange.

E represents a circular ring or plate having a large central opening, F, and provided with a series of small radial openings, G, between said opening F and its perimeter. On the upper side of the said ringEis placed a valvering, IVI, of similar size and shape,whieh valvering is made of leather" or other suitable inaterial. The said valve-ring and plate E are secured on the upper edge of cylinder A, between the saine and the shoulder D of cap B, the said valve-ring being `on the upper side of the ring or plate E and normally closing the openings G thereof.

I represents anv inner cylinder, the diameter of which is less than the diameter of the cylinder A. in the center of cylinder A, and has its upper end screwed into the central opening, F, of the ring E. The lower end of the cylinder I is also provided with screw-threads.

The said inner cylinder is arranged i l therewith, depends a stud, e.

K represents a valve-ring, which is similar 'to the Valve-ring II and is arranged against the lower edge of the inner cylinder, I.

L represents acireular plate or head which and is provided near its perimeter with a circular series of openings, M, which are arranged under the valve-ring K, and N represents a ring or collar which is screwed to the lower end of the inner cylinder, I, and is provided at it-s lower side with an inwardly-projecting annular iiange, O, which engages the lower side of the head or plate Il and secures the same and the valve-ring K iirmly in position on the lower end of the inner cylinder, I.

P represents a lower cap, which is similar in size-and shape to the upper cap, B, and is screwed to the lower end of the cylinder A.

which is provided with a ball-valve, S, in a valve-chamber, T, and has also a ball-valve, U, at its upper end in the lower end of the cap or head I).

The upper cap, B, has a central opening in whichv is screwed the lower end of a pipe, V. The upper end of the said pipe V is provided with a discharge-spout, W, and has a link, X, to which link is fulcrumed a lever, Y. To the inner end of the said lever is pivoted the upper end of rod Z, and the lower end of the said rod connects with the upper end of a tubular rod or pipe, A which eX- tends downward into the inner cylinder and is provided near its upper end with an opening, B', which communicates with a pipe, V.

'C' represents a packing, which is arranged in the pipe V near the lower end thereof, and through which the tubular rod A' extends. To the lower end of said tubular rod is secured a plunger, D', the construction of which is as follows:

a represents the upper section, which is substantially se1ni-spherical in shape, and is provided on its lower side with an annular channel, b, thereby forming a depending iiange, c.

inunicates with the channel. From the lower side of the section a, and formed integrally In the upper portion of the studv e. is a cavity, f, which is in the form of an inverted cone. The upper end of this cavity communicates with the forms the lower end of the inner cylinder, I,

From this cap P depends a suction-pipe, R,

The said flange has an opening, d, that comtubular rod A, and the lower end thereof has a semi-spherical recess, 7L.

t' represents a valve, which is arranged in the cavity f, and has a ball, 7s, at its lower end, which is socketed in the recess h. On opposite sides of the cavity f, and communicating with the same, are openings or channels g and I. The said opening or channel g is on a lower plane than the opening l, and the latter communicates with the channel b. The valve 7L is adapted to be moved against the opening g and l, so as to close one and open the other at the same instant.

m represents a lower section,which is semispherical in shape, and has its lower end truncated or flattened, as shown. On the upper side of the lower section is formed an annular flange or collar, n., which is adapted to enter the channel l) of section o.. A vertical central opening is made through the section m of sufficient diameter to receive a stud, e, and communicating with the said opening is an annular channel, o, having an opening, p, l n

f c aimon one side. The said channel o communicates with the opening g of stud e.

Arranged between the opposing sides of the sections a and m are a pair of leather packing or cylinder rings, s, which have their outer edges turned upward and downward, as shown, and thereby adapted to iit snugly against the inner side of cylinder I.

yr represents a nut, which is screwed onto the lower threaded end of stud e., and serves to force the lower section, m, upward on said stud and clamp the packing-rings rmly between said section m and upper section, a.

By operating the pump-lever the plunger may be caused to reciprocate vertically in the cylinder I.

The operation of my invention is as follows: On the upstroke of the plunger the valve 71y closes against the opening g, and thereby cuts off communication between the hollow rod A and the lower portion of the cylinder I. The pressure of the air in the upper portion of said cylinder I closes the valve 71, and a partial vacuum is formed in the lower portion of cylinders I and A, which causes the valves S U K to open, and thereby water is sucked into the lower end of said cylinders I and A. A portion of this waterpasses up through the annular space between said cylinder and finds its way through the valve-ring E into the upper portion of cylinder I, and is compressed by the upward movement of the plunger and forced upward thereby through the opening d Z and cavity f into the hollow rod A', and from the latter into the lower portion of the delivery-pipe V. The valves Il, K, U, and S close by their own gravity and by the pressure of the su perincumbent water when the plunger reaches the upper limit of its movement, and on the E ensuing downstroke of the plunger the valve g t' closes against the opening l, thereby opening communication between the lower portion of the inner cylinder and the tubular rod A. l A partial vacuum is formed in the upper portion of the cylinder I, which causes water from the cylinder A to be sucked into the upper portion of cylinder I through the valve plate or ring E and past the valve Il, and the water in the lower portion of cylinder I becomes compressed by the descent of the plunger, thereby keeping the valve K closed, and the water in the lower portion of cylinder I is 4 thus forced upward through the hollow rod i A into the delivery-pipe V.

From the foregoing description it will be E understood that the plunger both sucks and forces water at each stroke, whether up or down, and consequently a continuous stream l of water is discharged from the spout of the l discharge-pipe when the pump is in operation. Having thus described my invention, I
